The Enforcer handcuff key adapter serves as an extension of the handcuff key to facilitate the operation of the handcuff e.g. when wearing gloves or in stressful situations. The upper section with the key ring is rotatable and also has a locking pin for handcuffs. The handcuff key is fixed in the adapter by means of a union nut. The Enforcer handcuff key adapter with key ring is suitable for almost all standard handcuffs.
